Problems with Smell
Frequently Asked Questions
8. What are some of the common causes of smell disorders?
Most people who have a problem with smell have recently had an illness or injury. The most common causes are upper respiratory infections, such as the common cold, and chronic sinus or nasal disease. Other common causes are head injuries and exposure to toxic chemicals.
Nasal polyps can block the ability of aromas to reach the olfactory sensory cells. People with head and neck cancers who receive radiation treatment to the nasal area can also experience problems with smell.
